3. Connect the shuko plug into a 230V 50Hz socket or the crocodiles to the
conductors of the three-phase system (see previous pictures).
4. The key F4 permits to select one of the following limit values for the contact
voltage (which can be shown cyclically when pressing the key):
 50V (default).
 25V.
5. Press the START key once to execute a test injecting a current in phase with
positive half wave of the voltage.
Press the START key twice to execute a test injecting a current in phase with
negative half wave of the voltage.
WARNING
The P-PE measurement in a 230V System make flow a test current of 6A
approx. This may cause the tripping of magnetic protection switch with
nominal value lower than 10A and
will cause the tripping of RCD device . If
necessary effect the test upstream the switch or RCD.
